TRACK FOR STREET-RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 461,090, dated October 13, 1891.

Application filed April 2, 1891- Serial No. 38'7,435. (No model.)

To all whoflt it may concern:

Be it known that 1, WILLIAM CLARK Wool), a citizen of the United States, and a resident of Brooklyn, in the State of New York, have invented a new and useful Improvement in Tracks for Street-Railways, of which the following is a specification.

Thisimprovement is additional to my series of improvements in box girder-rails and their fastenings applicable in part as regards the clamp-ch airs to street-railway tracks in which rails of other patterns are used.

The present invention consists in the pro vision of such track with com promise-chairs, as hereinafter described, whereby clampfastened girder-rails may be readily connected with smooth and strong joints to flat rails of any approved pattern and permanently aligned therewith as to the treads of the re spective rails; also, in the novel construction of a compromise-chair for box and flat rails, as hereinafter-set forth.

Two sheets of drawings accompany this specification as part thereof.

Figure 1. of the drawings is a perspective view of the junction of a box girder-rail and a fiat rail effected by means of a compromisechair according to this invention. Fig. 2 is a perspective of the compromise-chair from a different point of view. Fig. 3 is an end View of the chair and rails, as in Fig. 1, wit-h a cross-section of the flat rail, a steel rail for curves, in the foreground. Fig. 4 represents a section of the chair on the line l 4, Fig. 3; and Fig. 5 is a sectional plan of those portions of the same at and below the line 5 5,

Fig. l. Fig. 6 is a partial end view of the chair in use, showing a different side bearing flat rail in cross-section; and Fig. 7 is another beveled on top. The particular rail represented in the drawings is one of myimproved box girder-rails of the section known assection B, and of the peculiar construction set forth in my specification forming part of Patent No. 443,470, dated December 23, 1890. Other box-rails having such flanges on their webs may obviously be substituted.

The compromise chair 0 (shown stripped in Figs. 2, 4, and 5) is preferably an iron casting, so as to be readily modified to fit dilferent sizes and patterns of rails, and in each pattern it is cast right and left by the customary transpositions.

Two seats a l) at top in line with each other are fitted, respectively, to the bottom of the flat rail A and to the interior of the clamped boxrail B. The seat a, excepting in some cases, a flange-receiving groove or grooves g, Fig. 6, is at or about the height of the lower level of the top of the seat Z). At the sides of the seat a a pair of strong lugs c afford lateral support to the end of the fiat rail A and align the gage-shoulder 0c of its tread t with that of the tread 25 of the boX-railB. The inner ends of said lugs serve also to prevent the protrusion of the rail B beyond the seat I). (See Fig. 1.) The seat 7) is preferably crowned, as in my other box-rail chairs, with a projection (l, fitted to the hollow back of the tread of the rail B, and the chair is provided immediately below the level of the rail-flangesf with boltholes 72. in its sides and with lateral projections 13, beveled at bottom and matching or opposing said beveled fiangesf 011 the boxrail. Being combined with my said patented box-rail in the example said projections are located out of reach of the lower edges of the rail-webs, and the sides of the seat portion of the chair above them are vertical or substantially vertical, so that the box-rail may be clamped in the manner and with the advantages set forth in my specification forming part of application, Serial No. 328,906, filed November, 1, 1889; but these details, together with said seat projection d, are not considered essential to a seat for box-rails as a part of the present invention. A horizontal strut s in the plane of the bolt' holes h re-enforces the open box-rail end of the chair against clamping strains, and the union of the upright portion of the chair with a suitable flat base 6 common to all is re-enforced by side braces 2' 0, appropriate to the inside and outside of the track, which are in turn braced on the fiat rail side by stays u, united at bottom with thebase e. A vertical transverse Wall to in the plane of the bracesi 0 extends upward from the base 6 to the seats a b, and is further connected with said seat a by bracket-struts 3 which merge into the lugs c at top. At the outer ends of the side braces 2' 0 the base e is provided on top with re-enforces r,within whose area a pair of square spike-holes 7L2, Figs. 2 and 5, are located at each side of the chair. Thechair O is so adapted to be spiked down upon a wooden cross-tie D, Figs. 1 and 3, by means of my improved spikes E, patented February 24, 1891, as set forth in my specification forming part of Patent No. 447,268. Other attaching devices and supports may be used, and other like modifications will suggest themselves to those skilled in the art.

The fiat rail A is spiked or bolted in customary manner to a wooden stringer F, the extremity of which is supported upon the cross-tie D and held in place by means of ordinary iron knees G, attached by spikes E pref erably of the same pattern as said spikes E.

The box-rail B is clamped fast upon the chair O by means of a pair of rigid wedgingclamps H, having beveled flanges fitted to said rail-flangesf and chair projections p and bolt-holes matching said bolt-holes h, and drawn toward the respective sides of the chair by a through clamping-bolt I, which,

ends of a flat rail and a girder-raih'the latter having laterally-projecting flanges at bottom, and with a pair of flanged clamps and a clamping-bolt, of a compromise-chair having at one end a seat fitted to the bottom of the fiat rail and upwardly-projectinglugs at its respective sides and at the other end a suitable seat for the girder-rail, lateral projections below its flanges to coact with said clamps, and transverse bolt-holes to receive said clamping-bolt, substantially as hereinbefore specified. 4

2. A compromise-chair having at one end a flat-rail seat and upwardly-projecting lugs at its respective sides and at its other end a box-rail seat and provided below the latter with lateral projections and transverse boltholes and at bottom with a suitable base common to all, substantially as hereinbefore specified.
